Product Details
Taking the high level pure quartz sand and industrial Alumina as its raw materials, Fused mullite is melted through over arc furnace, which appears white, low left carbon and well developed needle crystal. With its excellent performance of heat- resistance, shock- resistance and abrasion resistance, it is widely used in the industrial areas, such as lining bricks of the glass kiln, mullite bricks of the no alkali glass settling pond, bricks of the large blast furnace, silicate bricks of the blast furnace, ceramic kiln tools, saggar, slab and petrochemical industry, ect. It is the high level raw material of the refractory materials. We can produce according to our clients’ requirements.
Applications
a) Refractory materials
Refractory castables,corundum-mullite refractory brick,hook refractory material,and other refractories;
b) Ceramics
Mullite ceramic kiln tools, saggar, slab and petrochemical industry, ect
